Impulse #1

An impulse takes raw data, uses signal processing to extract features, and then uses a learning block to classify new data.

Description	Recommended
Images Officially Supported Processes discrete images for object detection or classification.
Time series data Officially Supported Operates on time series sensor data like vibration or audio data. Lets you slice up data into windows.
Pre-processed features Officially Supported Processes pre-processed features, or non time-series data.

Did you know? You can bring your own DSP code.

Image Officially Supported Preprocess and normalize image data, and optionally reduce the color depth.	Edge Impulse
Flatten Officially Supported Flatten an axis into a single value, useful for slow-moving averages like temperature data, in combination with other blocks.	Edge Impulse
Audio (MFCC) Officially Supported Extracts features from audio signals using Mel Frequency Cepstral Coefficients, great for human voice.	Edge Impulse
Audio (MFE) Officially Supported Extracts a spectrogram from audio signals using Mel-filterbank energy features, great for non-voice audio.	Edge Impulse
Spectral Analysis Officially Supported Great for analyzing repetitive motion, such as data from accelerometers. Extracts the frequency and power characteristics of a signal over time.	Edge Impulse
Spectrogram Officially Supported Extracts a spectrogram from audio or sensor data, great for non-voice audio or data with continuous frequencies.	Edge Impulse
Audio (Syntiant) Officially Supported Syntiant only. Compute log Mel-filterbank energy features from an audio signal.	Syntiant
IMU (Syntiant) Officially Supported Syntiant only. Great for analyzing repetitive motion, such as data from accelerometers. Extracts the frequency and power characteristics of a signal over time.	Syntiant
HR and HRV features Officially Supported Process PPG or ECG data into heart rate and heart rate variability features. This block is available for testing but requires an Enterprise license to deploy.	Edge Impulse
Raw Data Officially Supported Use data without pre-processing. Useful if you want to use deep learning to learn features.	Edge Impulse
